The ESS battery systems have a prescribed design life of 25 years, but the battery modules, electrolyte, plumbing, and other components may well last for decades longer with proper maintenance.

Closed-loop pumped-hydro storage offers more chances to minimise environmental effects on water sources and overcomes the problem of finding suitable sites. According to an Australian research team, closed-loop systems could prevail on open-loop systems in the future and this trend is confirmed by another group of scientists from the United States.

Multiple factors affect lifespan of a residential battery energy storage system. We examine the life of batteries in Part 3 of our series.

As solar deployment increases, concerns about price cannibalisation continue to be more and more relevant. Large-scale solar generation during midday hours may result in curtailment or unprofitable wholesale power prices. As supply increases, the economic viability of solar PV projects could fall into question.

Buildings are considered to be a major driver of emissions. In addition to the predicted billions of square meters of space that will be built across the world over the next decade, most developments standing today will still be around in 2050. Thus, retrofitting existing structures is seen as a key sustainability target. In the fourth quarter of 2021, pv magazine’s UP Initiative will focus on the role that solar and energy storage can play in greening the world’s urban spaces.

U.S. start-up EnerVenue has secured funding to build a gigafactory to produce nickel-hydrogen batteries for large scale renewable and storage applications. The battery has an efficiency ranging from 80 to 90%, depending on the cycle rate, and its energy density per square foot is equal to, or better than lithium-ion batteries, according to the company.

The sustainability claims of a crowdfunded ‘e-textile’ range launched by Art by Physicist are borne out by the fact each garment will be printed on demand.

Rising efficiencies and the plummeting cost of solar modules over the past few years, recent months notwithstanding, are leading innovators toward ideas that may look unusual in the current tracker-dominated world of large-scale solar parks. Advocates of the new approaches argue that they leave traditional models looking decidedly flat by comparison.

Drones have already established themselves in industries as disparate as warfare, wedding photography, and burrito delivery, and increasingly the solar sector is taking the high road, too. Combined with thermal imaging, drones have the potential to obviate expensive maintenance costs for large-scale solar plants, as well as C&I and growing niches like floating PV. But how useful are they, and what role does AI play in making the most of a bird’s eye view?

Multiple factors affect the productive lifespans of residential solar inverters. In the second part of our new series on resiliency, we look at PV inverters.
